Transmission

Transmissions and the hardware around them for classic truck swaps — 6R80, 10R80 and Tremec, plus shift levers, crossmembers and cooler kits.

The transmission is the half of a swap people underestimate. It needs a crossmember that fits your truck, a cooling circuit the donor truck used to provide, and a shifter that works in an old cab.
